Missing your big sister’s wedding is one thing, but the Kardashian brother just dissed his family in the worst possible way.

In a fairly unsubtle message to the world – and more specifically to his family – Rob Kardashian has unfollowed everyone on his Twitter account except two lucky people.

The 27-year-old’s mum, Kris Jenner, 58, and his littlest sister, Kylie Jenner, 16, made the cut, meaning Kim, Kourtney, Khloe and Kendall have all been deleted from his follow list (and his life?). The troubled reality TV star also briefly followed an array of, er, ‘adult film stars’ but quickly deleted them (presumably the sight of them sitting alongside his mum made him have a re-think), and he’s also deleted all but three of his most recent Tweets.

It’s the latest temper-tantrum from the lad who recently ditched the ceremony as Kim married rapper Kanye West in Florence because he apparently felt too self-conscious about his size to appear in photographs.

A source said how Rob’s last minute departure caused rows among the Kardashian family and he was seen booking his flight back to LA in tears.

Celebrity trainer Gunnar Peterson told TMZ he had received a text message from Rob when he returned from Italy.

He said Rob is determined to “hit the ground running” with a new fitness regime and wants to work out every day until he feels slim again.

Rob previously lapsed his workouts and visited the gym just a few times before flying out to Europe for the wedding, but is now determined to get into a regular routine.

Gunnar told the website he will show his client “no mercy” and plans to put him through an hour of high-intensity full body exercises, cardio and resistance training every day.

He added: “Rob is locked and loaded.”

It was previously claimed the 27-year-old star – whose over-eating began following his break-up from Rita Ora in 2013 – allegedly got into an argument with Kim over her lavish wedding extravaganza, which he branded “superficial bulls**t”.

Things kicked off between the siblings during a lunch at designer Valentino’s Château de Wideville in Crespières, France, and Rob headed for the airport shortly afterwards.

An insider said: “Rob is not in a good place right now at all and his family should be very worried about him.

“He was embarrassed to go to the wedding in the first place because of his weight gain and to be ridiculed by Kim and basically rejected has put him over the edge.”
